back arc basin wikipedia : Back-arc basins are geologic basins, submarine features associated with island arcs and subduction zones.They are found at some convergent plate boundaries, presently concentrated in the western Pacific Ocean.Most of them result from tensional forces caused by oceanic trench rollback (the oceanic trench is wandering in the seafloor direction) and the collapse of the edge of the continent.The back-arc region is the area behind a volcanic arc. In island volcanic arcs it consists of back-arc basins of oceanic crust with abyssal depths, which may be separated by remnant arcs, similar to island arcs. In continental arcs the back-arc region is part of continental platform, either dry land or forming shallow marine basins.The Lau Basin is a back-arc basin (also addressed as “interarc basin”) at the Australian-Pacific plate boundary.It is formed by the Pacific plate subducting under the Australian plate.The Tonga-Kermadec Ridge, a frontal arc, and the Lau-Colville Ridge, a remnant arc, sit on the western and eastern sides of the basin respectively.Back-arc basins (or retro-arc basins) are geologic features, submarine basins associated with island arcs and subduction zones.They are found at some convergent plate boundaries, presently concentrated in the Western Pacific ocean.Most of them result from tensional forces caused by oceanic trench rollback and the collapse of the edge of the continent.Pages in category "Back-arc basins" The following 13 pages are in this category, out of 13 total. This list may not reflect recent changes ().Foreland basins can be divided into two categories: Peripheral (Pro) foreland basins, which occur on the plate that is subducted or underthrust during plate collision (i.e. the outer arc of the orogen) . Examples include the North Alpine Foreland Basin of Europe, or the Ganges Basin of Asia; Retroarc (Retro) foreland basins, which occur on the plate that overrides during plate convergence or ...Back-arc basin is part of WikiProject Geology, an attempt at creating a standardized, informative, comprehensive and easy-to-use geology resource.

B This article has been rated as B-Class on the project's quality scale.Media in category "Back-arc basins" The following 7 files are in this category, out of 7 total.Back-arc basin, submarine basin that forms behind an island arc. Such basins are typically found along the western margin of the Pacific Ocean near the convergence of two tectonic plates. Back-arc basins are sites of significant hydrothermal activity, and the deep-sea vents that occur in theseThe area between the trench and the arc is the forearc region, and the area behind the arc (i.e. on the side away from the trench) is the back-arc region. Initial theories proposed that the oceanic trenches and magmatic arcs were the primary suppliers of the accretionary sedimentation wedges in the forearc regions.

Back-arc basins (or retro-arc basins) are geologic features, submarine basins associated with island arc s and subduction zones.They are found at some convergent plate boundaries, presently concentrated in the Western Pacific ocean.Most of them result from tensional forces caused by oceanic trench rollback and the collapse of the edge of the continent.A Back-arc Basin is a geological formation that occurs on the ocean floor. This marine formation is most commonly identified along subduction zones, which occur where one tectonic plate moves beneath another, and island arcs, which are a kind of archipelago made up primarily of volcanos.Cross-section sketch showing the development of a back-arc basin by rifting the arc longitudinally. The rift matures to the point of seafloor spreading, allowing a new magmatic arc to form on the trenchward side of the basin (to the right in this image) and stranding a remnant arc on the far side of the basin (to the left in this image).Looking for back-arc basin?

The region between an island arc and the continental mainland formed during oceanic plate subduction, containing sediment eroded from both Explanation of back-arc basinThe presence of these Early-Middle Ordovician (480 - 460 million year old) back-arc basin rocks in direct or faulted contact with rocks of the Laurentian shelf and slope-rise in the southern Appalachians suggest they were built on the margin of Laurentia, beyond the edge of the continental shelf-slope break.back-arc basin The zone of thickened sedimentation and extensional tectonics which lies behind an island arc.Sedimentation in back-arc basins can be very varied, ranging from pelagic through turbidites to alluvial fans, although volcaniclastics (see CLAST) are common.Various convective systems have been postulated to explain extension, which is oriented parallel to the compression in a ...MARGINAL BASINS & BACK ARC SPREADING . Marginal basins are a common feature of the Western Pacific. Examples (north to south) are the Sea of Japan, the West Philippine Basin, the Parace Vela & Shikoku Basins, the Mariana Trough, the Woodlark Basin, the Fiji and Lau Basins. By contrast marginal basins are rarer in the Eastern Pacific.背弧海盆(はいこかいぼん、英: back-arc basin 、略称 BAB 、別名 retro-arc basin )とは、地質学的事象であり、その成り立ちにおいて島弧や沈み込み帯と関連がある海面下の盆地である。 西 太平洋で比較的新しい時代に集積された複数のプレートの境界領域でこれらを見ることができる。The back-arc region is the area behind a volcanic arc. In island volcanic arcs it consists of back-arc basins of oceanic crust with abyssal depths, which may be separated by remnant arcs, similar to island arcs. In continental arcs the back-arc region is part of continental platform, either dry land or forming shallow marine basins.
